Reverend Walter Kim, Mary Evelyn Tucker, and John Grim introduce the Yale Forum on Religion and Ecology and trace their personal paths into faith-based environmentalism — Kim through evangelical ministry, Tucker and Grim through their teacher Thomas Berry and encounters with indigenous traditions in the northern plains and across Asia. The conversation surveys a wide landscape of religious environmental work already underway: the NAE's 1970s creation-care resolution, Ecumenical Patriarch Bartholomew's water symposiums, Pope Francis's Laudato Si', and evangelical initiatives like the Lausanne Movement, World Vision, and Kim's own account of visiting farmers in Malawi. It closes with Tucker's reminder that, for all this hopeful groundwork, we're at one of the most critical moments in human history.
